This structure is supported upon the casing and insulated therefrom 'by an insulating bushing 17 screwed upon the shell 12 and having a flange l8 engaging the outside ofthe caselectrically connected with the center lam contact by means of the screw 15, while the clamp 11 being in engagement with the back of the threaded shell 12, is electrically connected thereto, whereby, when the electrical conductors l9 and 20 are secured in position, the threaded shells and the center lamp contacts are all electrically connected. The clamps of the'shell which support a lamp in a vertical position, have extensions thereon which carry binding posts 21 and 22, to which the leading-in wires 23 and 24 may be readily secured. Extending between the clamp carrying the binding post 22, and one of the clamps 8, is a conductor 25 and extending between the clamp carrying the binding post 21 and one of the clamps 11, is a'conductor 26.

I have illustrated in Fig. 5, a cluster in which only two lights are provided. The structural features, however, of this cluster are substantially the same as just described. In Fig. 6 I have illustrated, diagrammatically, one means of electrically connecting the contact of a three-light structure. In this figure it will be noted that a conductor 27 extends between the center contacts of two of the lamps and a conductor 28 extends be tween the ring contacts of two of the lamps, the leading-in wires being connected by binding posts 21 and 22. By this arrangement, the three lamps are connected in series. In Fig. 7, I have shown a series arrangement for four lamps and in Fi 8 I have shown a multiple connection for four lamps. From these illustrations, one skilled in the art will readily understand how to apply my inven- -'tion tothe various requirements of cluster work.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is: 1. The combination with a support, of a casing connected thereto, a plurality of in' sulatim blocks, lamp-receivers and their associated. contacts arranged within the casing and-supported thereby, means for securing each of said insulating blocks to its corre-' sponding lamp-receiver and associated contacts, a pair of clamps attached to opposite sides of each of said blocks, and conductors extendlng between said receivers and connected with the contacts thereof by means of i said clamps. 2. The combination with a support, of a l casing removably connected thereto, a plurality of insulating blocks, lamp receivers and their associated contacts arranged in and wholly supported by said casing and attached to opposite sides of each of said blocks and conductors extending between said receivers and connected with the con tacts thereof by means of said clamps, one pair of said clamps carrying binding posts for the leading-in wires.

3. In a cluster socket, the combination with a support,- of a casing removably connected therewith, a plurality of shell-contacts carried by said casing and insulated ciated with each ofsaid shell-contacts, an in sulating block between each pair of conductor-clamps, a screw for securing each of said insulating blocks with its pair of conductor-clamps to the corresponding shellcontact, and a center contact carried by each of said screws, one of each pair of conductor .clamps being electrically connected with its associated shell-contact, whilethe other con- 'ductor-clamp of each pair is electrically connected to the corresponding center contact.

4:. In a cluster socket, the combination with a support,'of a casing removably connected therewith, a plurality of shell-contacts carried by said casing and insulated therefrom, a pair of conductor-clamps associated with each of said shell-contacts, an insulating block between doctor-clamps,

a screw for securing each of said insulating blocks with its pair of condnctor-clamps to the corresponding shellcontact, a center contact carried by each of saidscrews, one of each pair of conductorclamps being electrically connected with its associated shell-contact, while the other conductor-clamp of each pair is electrically tact, conductors held between said conductor-clamps and insulating blocks for electrically connecting said lamp-contacts, and a pair of binding-posts for the leading-in wires carried by one pair of said clamps.

5. The combination with a support, of a casing removably connected thereto, a plurality of lamp receivers arranged in and wholly supported by said casing, eachre- (ft-ll er comprising a threaded lamp shell and a center, contact, an insulating base, a .pair of clamps, a common binding screw for connecting said parts together, one of said clamps being electrically. connected with the center lamp contact through said binding screw and the other clamp being electrically connected with said threaded shell, electrical connections extending between the clamps connected with said center lamp contached to said blocks, a pair of clamps attherefrom, a pair of conductor-clamps asso-.

connected to the corresponding center con each pair of conv laets, electrical connections extending heplurality of socket elements, an insulating- 'olock and a pair of renductor-elainps 1 01 each socket element, said (30ndtlUtObClillXlPS i being secured to said lllSUlZltlllg'ldUUli upon opposite sides thereof, and ineans for insulatiu the socket elements from the casing.

10. A lamp cluster comprising a casing illHl a plurality of socket elements, each elelilil'it comprising a threaded shell, an insulating block, conductorclamps mounted upon oppusite'sides of said block, a center i-oi'itaet, and a clamping screw, for holding the parts together in operative relation.

1 .t. In a lainpcluster, a plurality of socketrlennrnts eoinprising each a shell-contact, an insulating block, a pair of condnctonclamps mounted upon opposite sides of said block, means for holding the parts together, and a renter contact carried by said holding in ans.
